43 Interplay between the compatibilization of polyethylene-graft-polystyrene and the composition of LLDPE/PS blends in the foaming behaviour
关键字：?Polyethylene-g-polystyrene
Polyethylene-g-polystyrene (PE-g-PS) copolymers, which were prepared by the combination of the ROMP and ATRP method, were utilized to compatibilize LLDPE/PS blends. On one hand, the effect of PE-g-PS on the morphologies of LLDPE/PS blends was investigated. On the other hand, the influences of branch length and added amount of PE-g-PS on the cell morphology of foamed LLDPE/PS blends with different ...

Construction of Small-Diameter Vascular Graft by Shape-Memory and Self-Rolling Bacterial Cellulose Membrane
关键字：Bacterial Cellulose Membrane
Bacterial cellulose (BC) membranes with shape-memory properties allow the
rapid preparation of artificial small-diameter blood vessels when combined
with microfluidics-based patterning with multiple types of cells. Lyophilization
of a wet multilayered rolled BC tube endows it with memory to recover
its tubular shape after unrolling. The unrolling of the BC tube yields a flat
membr...

The thermal characterization of PB-g-(PB; PEO) dual brush crystalline-amorphous graft copolymers
Dual brush crystalline-amorphous (C-A) graft copolymers (PB-g-(PB; PEO)) with various PEO chain lengthswere synthesized by anionic and anionic ring open polymerization techniques, and their thermal analysismeasurements were performed (Figure 1).

Preparation and Properties of Biodegradable Blends from Poly(3-hydroxybutyrate) and Modified Corn Starch
关键字：Poly(3-hydroxybutyrate), Corn starch, Graft copolymers, Blends
Poly(3-hydroxybutyrate) (PHB) is a biodegradable polyester produced by the fermentation of bacteria. However, it is a brittle and expensive material. To lower its cost, PHB was blended with the corn starch. Yet, due to their ...
